ROLLER-SCREEN.

Application filed June 21,1917.

To (m. 10/! am. it may concern Specification of Letters Patent.

lie. it. known that I, EnunND ll. SI'MONTON,-

a citiz n f the nited States, residing at (bu-v, in thccounty oi Deuel, Statev of South Dakota, have invented certain new and use ful Improvements in Roller-Screens; and I do hereby declare the following to be a full, clear, and exact description of the invelr tio'n, such as will enable others skilled in the art to which it a]' pertains, to make and use the same.

This invention relates to roller screens.

The object of the inrentirm is to provide a. practical roller screen to be inoui'ited upon the outside of a window frame. so that the s reening; may be. drawn across the .-vindo\\-' opening and 'lastened. while leaving the. window sash tree for muni 'nilatim at tlu. will. of the occupants of the house.

With the above general object in view, and such others relating to the details of construction of the various parts, as may hereinafter appear, my invention will now be fully forth and described, reference being had to the accompanying drawings.

In the drawings Figure 1 is a perspective view showing the screen mounted upon. the outside of a window casing,

Fig. 2 is an enlarged view of the roller mechanism from which the cover has been removed,

Fig. 3 is a section on line. 3 3 of Fig. 2,

Fig. 4 is a detail of one of the slide. mom hers,

Fig. 5 is a detail of the marginal construction of the screen, and

Fig. 6 is a section on line 66 of Fig. 4:.

Referring morev particularly to thedrawings, 1 represents the window casing as viewed from the outside. Secured to the upper cross" head of the casing 1., is a base plate 2 which extends entirely across the casing, and carries at its ends the bearing blocks 8. Mounted in the bearing blocks 3 are the stub shafts 4 which are keyed against rotation therein by means of the cross pins 5 which are removably passed through the outer ends of the stub shafts and are locked into position by means of the clips 6. Between the bearing heads 3 the stub shafts have mounted thereon a roller 7 which is provided at eachend with metal housings 8 which are of the same diameter as .the roller and house the coil springs 9. One end of each of the coil springs is connected latci'lted M at. 5, 191 8.

to its respective housing, and the, opposite end is lined to [he corres mluling stub shaft, so that as the roller rotated to witl'ulrau' the length of the screenil'ig 1.0, the springs are wound so as to increase their tendency to rewind the screening 10. The length of the. screening 10 is secured at. one end to the roller 7, and on its opposite end is provided with atransversc metal binding 11. The binding 11 operates in a pair of guide ways which extend from top to bottom of the window casing at its sides. Said guide ways eons'iist oi? sheet metal strips liar .ing the longitudinal outwardly bent channels 13. and having the foot bases 1-1- formed along their onten edges so as to permit thiinner ed; .o staiul w y from the. casing 1 wire i the foot bases are secured to the latter. The extremities of the binding 11 are upturned so as to ride in the channels 13, and the screen. length 10 is furthermore provided at intervals with the cleats 1.5 which are also right angularly bent so that While the arm which is attached to the screening rides below the spaced portion of the guide, the other arm operates in the channel 13. In order to secure the guide strips to the casing, I provide the clips 16 which comprise base portions which bear upon the foot sections of. the guide. strips and are apertured to receive fastening screws, and the hooked portions 1.7 which oveilic the channels 13, thereby reinforcing the latter and providing a stop to the accidental. si'ircading of the space- 1 portion of the guide strips.

In order to secure the screen in its ex-- tended position, I provide the pivoted latch. members 18 on the binding stripsll and the headed bolts or screws 19 in the sill, with which the. latches may be engaged.

The winding structure is housed by a sheet metal casing 20 which secured across and conforms to the marginal edges of the hearing blocks 3, and a suitable wearing strip 21 is secured along the lower edges of the easing 20, said wearing strip being of flexible material or fabric which will keep closed the slot or opening through which the screening length passes.

The roller screen of the above described invention provides a simple and practical device, in. that the nature of its manufacture and assemblage permits its use upon the outside of a window, rather than on the inside, thereby increasing the efficiency of the screen. Thus, it is only necessary to remove the roller screening at such compareiively infrequent periods that it may be new cssnry in Wash the windows or otherwise gain access to the exterior sides of the sushi-s. At all other times the sashes may he raised or lowered without disturbing the screen. \Vhen cold weather renders the screens nnneeessnry, they may he released or rolled up within the casing 20, and remain ll'ins ilisposml until the Following warm season.

What Lelnim us my invention is:----- 1. A roller screen, comprising in combi nation, a luise plate, :1 pair of bearing blocks on the enils of the base plate, stub shafts mounted in said hearing blocks, n roller rotatable up n the stub shaft, 2 housing, cnrl'l((l by enrh enil of the roller and fori'i'iing rontii'iuntions thereof of equal diameter therewith, l nul springs abutting the ends of (he rollrr and secured to the eorresponih ing roller housing 1\ll(l to the stub shafts, within the housing, so thnl when the screen is uni-oiled, the springs are ti htly wrnp ed, length of sereenin secureti to the rolfers, nlul overlying the l iousing, and u easin Il'l()lllli'(',(l on the bearing blocks and secure to the base plate to completely shield the screen.

2. A roller screen, comprising in combination, :1 spring roller, H, length of screening llu-reon, u binding on the lower end of the screen, clips along the longitudinal edges of the screen, the outer extremities of the binding and the clips being turned outwardly :it right angles, and guide strips mounted to rereire the edges of the screen, and having right ungulnrly directed channels to receive right ungnlurly turned ends of bindinn nn l elips.

In testimony whereof, I uflix my signature in the presence of two witnesses.
